Thanks to this thread and in particular [B]carl750[/B] for the inspiration/help on how to replace the split hinge pins on the Giulia Super with a much better solution.
What needs to be done is to knock out the old split pins and tap in four sleeve bearings into each hinge. These bearings are Bronze-Backed PTFE Plastic Bearings with Steel Shell. They are designed to be self-lubricating bushings they are rolled bushings composed of a steel backing, for structural strength, with bonded layers of sintered bronze and PTFE (Polytetrafluoroethylene similar to Teflon) for a maintenance free bearing surface. These bushing work best when fit very snugly. This forces the split in the bearing to close thereby fitting snugly on the shoulder bolt. Since the hole in the hinge (as carl750 noted) is larger then it should be steel shim material needs to be inserted along with the bearing to ensure a sung fit. Then Stainless Steel Shoulder Screws are tapped into the hinge and locked down with a stainless steel nylon locking nut and washer.

Yes, nice. At a lesser level, you can replace a worn pin in a Berlina or Super with a regular 8mm bolt. Fixing wear in the holes is tougher, as above.

I have to weld n grind my driver's doo latch every couple years to account for hinge wear. Still, way better than GTVs since this stuff is steel, not aluminum.
